title: [Primary cancer of the liver].
abstract: The epidemiologic and pathogenic aspects of primary hepatic malignancies are discussed. The role of viruses in the etiology of the disease is stressed. Imageology methods have a preponderant role for diagnosis and treatment options. Liver resection has a one years survival between 60 and 80% and a five years survival of 20 to 40%. A good surgical results is expected for tumors with no more than 5 cm in diameter, encapsulated and without vascular invasion non-cirrhotic livers, large tumors can also be removed. Surgical resection margin should be of 1 cm. For cirrhotic livers, a good liver function is needed (Child A-B) and no safe major resection can be done. History of bleeding portal hypertension has a negative role in the outcome. Liver transplantation should be limited to selected case, in which the tumors are small and asymptomatic (incidental). For larger tumors, long term results are not good with invariable recurrency of the tumor.
